Basically my old HDD died from bad sectors and I had to format and install Windows 7 Enterprise on a back up hdd that was flooded with useless documents from the past.

Went ahead done what I had to do and left Windows to check for updates, Steam install some games and League of Legends update.

However everything finished but Windows was still checking for updates and I noticed the svchost.exe (netsvcs one) uses about 1.5 GB out of 4 RAM. Immediately knew that this was caused by the Windows Update service that's under it.

However turning Windows Update off is never a smart thing to do and I don't have the kind of time to manually download updates.

I know that it will probably blast me with 200+ updates (has happened in the past but never used up so much RAM and finished way faster than 6 hours with all my usual post installation stuff.

Anyways some info you should probably know:
-I'm using a Wireless adapter (TP-LINK TL-WN722N) and I have read threads here that Windows Update would sometimes fail to do what it should with Wireless adapters, unfortunatelly that isn't an option at the moment.
-Resetting Windows Update manually and through Fix It doesn't work.

So first thing I'm looking at is updating the Windows Update client, please do tell if you think otherwise, or if not link me to the newest Windows update client or probbably any hotfixes that could fix the problem (never done this before and wouldn't want to mess up, so I decided to ask you guys )

Another short question I have:
Does editing the group policy to stop Windows Update from auto restarting after updates still work as before? (I have not done this yet on this computer yet just want to know)

Hi Qualtrox,
might be due to fact that Enterprise and Ultimate, are different versions.
If you using the Ultimate key on an Enterprise install, or visa versa, then it will hang as its failing validation.
We can check if you run this too, copy/paste the outputhttp://go.microsoft.com/fwlink/?LinkID=52012

The only place you can buy that key is Directly from MS.
IF you purchased it from anywhere else, then its non-genuine

From your report
DNS auto-discovery: KMS name not available
ActiveX: Not Registered - 0x80040154
Admin Service: Not Registered - 0x80040154
It currently may not show the non-genuine logo,
but in less tan 6 months it will

The KMS error, (its looking for the update server), is why its not updating.

Just wanted to let you know I just managed to fix this by doing a manual update to the newest windows update client (this fixed the problem with the infinite checking for updates) and downloading a hotfix i found on a forum with a very similar question (this fixed high RAM consumption).
Both the update and hotfix are from Microsoft and I will provide links when I get back home to help out anyone facing same problems.

Now it's half way through installing 261 updates.
Had absolutely no idea about the key though, but it seems to be a mess up in the installation (I have multiple Windows installations on multiple USB sticks marked with editions and keys, wen't for the choice of Enterprise since it wouldn't bother me to upgrade windows to a newer os).
However it had absolutely nothing to do with the Windows Update problem.

However thank you for giving a possible solution that could help a fellow SevenForums user and for helping me remember where I got that key from

So last question, will the key im using now cause me any problems in the future?
